问题描述

我不是专家,但我需要在我的 Woocommerce 产品页面中更改“失控”产品的价格行程。

  1. 我发现如何将价格更改为“已售出”(并且有效)
//Change price to 'sold'
    
add_filter('woocommerce_product_get_price','change_price_regular_member', woocommerce_currency_symbols, 10, 2 );

function change_price_regular_member( $price, $product)
{
        if (!$product->is_in_stock())
            $price = "SOLD";
        return $price;
}
  1. 我试图隐藏我的货币符号(将 $SOLD 更改为 SOLD)
add_filter('woocommerce_currency_symbol', 'change_existing_currency_symbol', 10, 2);
function change_existing_currency_symbol( $currency_symbol, $currency ) {
    global $post, $product;

    if (!$product->is_in_stock() ) {
        switch( $currency ) {
             case 'USD': $currency_symbol = ''; 
             break;
        }}
   
    return $currency_symbol; 
}

它不起作用

解决方案


使用woocommerce_get_price_html如下钩子代替(这将替换格式化的显示价格和货币)

add_filter('woocommerce_get_price_html', 'change_sold_out_product_price_html', 100, 2 );
function change_sold_out_product_price_html( $price_html, $product ) {
    if ( ! $product->is_in_stock() ) {
        $price_html = __("SOLD", "woocommerce");
    }
    return $price_html;
}

代码位于活动子主题(或活动主题)的 functions.php 文件中。它应该更好地工作。


与您的评论相关的补充:

对于您的第二个代码片段,请尝试以下操作:

add_filter('woocommerce_currency_symbol', 'change_existing_currency_symbol', 10, 2);
function change_existing_currency_symbol( $currency_symbol, $currency ) {
    $product = wc_get_product( get_the_ID() );

    if ( is_a( $product, 'WC_Product' ) && $currency === 'USD' && ! $product->is_in_stock() ) {
        $currency_symbol = ''; 
    }

    return $currency_symbol; 
}

它应该有效。如果您想在产品缺货时使其适用于所有货币, && $currency === 'USD'请从IF声明中删除
